RCBT-63H+

Overview

The RCBT-63H+ is a surface mount bias tee from Mini-Circuits, designed for RF applications up to 6 GHz. It provides high DC voltage and current handling capabilities with low insertion loss. The device supports up to +50 V DC voltage and 2.5 A DC current while accommodating RF input power up to +30 dBm (1 W). Enclosed in a compact TT1224-2 package measuring 0.31x0.28x0.07 inches, it integrates DC biasing into RF signal paths efficiently.

Feature Summary

• Surface mount construction for automated assembly integration
• High DC voltage handling capability up to +50 V
• Robust DC current capacity of 2.5 A
• Low insertion loss design for minimal signal degradation

Applications

• RF circuit biasing in wireless communication systems
• Test and measurement equipment requiring integrated DC bias
• Broadband RF amplifier powering applications

Procurement Notes

Verify the specific datasheet version for the RCBT-63H+ to confirm electrical parameters such as insertion loss and return loss at target frequencies. Ensure the application environment does not exceed the specified +50 V DC voltage or 2.5 A DC current limits. Confirm that the RF input power remains within the +30 dBm maximum rating to prevent device damage. Check compatibility with the TT1224-2 footprint during PCB layout.

Selection Notes

Select the RCBT-63H+ when a compact surface mount solution is required for biasing RF components operating up to 6 GHz. This component is suitable for designs needing high DC current handling alongside standard RF signal transmission. Consider the physical dimensions of the TT1224-2 package against available board space. Evaluate if the low insertion loss characteristics meet the system's signal integrity requirements compared to discrete biasing methods.

Part Context

The RCBT-63H+ belongs to Mini-Circuits' family of surface mount bias tees, which are passive RF components used to inject DC power onto RF lines without disrupting the signal. These devices are commonly found in RF front-end modules and test fixtures where space constraints necessitate integrated solutions over discrete resistor-capacitor networks.

Replacement Considerations

Mini-Circuits offers other models in the bias tee series, such as the RCBT-6+ or RCBT-18+, which may differ in frequency range or current handling. Verify that any substitute part matches the required DC voltage, current, and RF power specifications. Ensure the replacement component fits the same TT1224-2 or compatible footprint to avoid PCB redesign.
